JNCIA-ER

I am taking up my JNCIA-ER on the 29th NOv. I have gone through the fast track pdf once. Could you give me any feedback as to what else I need to go through? Haven't got much hands on thats my only worry. Planning to read through the lab guide which juniper thinks is optional. Any recommendations as to what should go through or going through the main pdf twice would do for 70% ?
